We build API integrations that connect your tools and automate workflows. Get a fixed price and a working integration in 8-12 weeks.
IRPR is an experienced api integration development company. We build custom integrations between systems like Salesforce, HubSpot, Shopify, Stripe, and AWS using Node.js, Python, and Go. Every integration is designed for reliability and scalability.
We ship working API integrations in 8-12 weeks. Pricing is fixed from $80K to $250K depending on complexity. We handle compliance: HIPAA for healthcare, PCI-DSS for payments, SOC 2 for SaaS, and FERPA for education.
Our clients are CTOs who need to connect legacy systems to modern APIs, product managers launching a SaaS MVP that requires third-party integrations, and operations directors automating data flows between 3+ platforms. They hire us because we deliver on time and own the code.
Types of software we ship.
REST API integration
Connect systems using RESTful APIs. We handle authentication, rate limiting, and error retries. Integrates with Stripe, Twilio, and more.
GraphQL integration

Why you need an experienced api integration development company
A broken integration costs you time, data, and customers.
IRPR has shipped 200+ integrations across 50+ countries. We know how to handle rate limits, timeouts, and data format mismatches. Our integrations are built with retry logic, monitoring, and alerting from day one.
We use tools like Sentry for error tracking, Datadog for performance monitoring, and Postman for testing. Every integration includes automated tests and a rollback plan. You get a system that works under load.
The difference between IRPR and generic dev shops
Most agencies overpromise and underdeliver on API work.
Generic dev shops often start coding without a clear integration design. They skip error handling, ignore rate limits, and leave you with a fragile connection that breaks on every API update.
IRPR uses a structured Roadmap phase (week 2) to map every endpoint, define data flows, and plan for edge cases. We write integration tests before we write the integration code. Your system stays stable.
- No integration design phase
- No error handling for API timeouts
- No monitoring or alerting
- No automated tests
- Hourly billing with no cap
- No compliance review
- Roadmap phase maps every endpoint
- Retry logic with exponential backoff
- Sentry and Datadog monitoring
- Integration tests in CI/CD pipeline
- Fixed pricing from $80K
- HIPAA, PCI-DSS, SOC 2 compliance
Our API integration process
We follow a 4-phase process that guarantees a working integration.
Every integration starts with a discovery call where we map your systems and data flows. Then we build a Roadmap that defines endpoints, authentication, and error handling.
We build the integration in 2-week sprints with demos at the end of each sprint. You see progress and give feedback. After testing and deployment, we hand over the source code and documentation.
What ships with every API integration
You own everything. No black boxes, no lock-in.
When we finish your integration, you get the complete source code, deployment scripts, and API documentation. You can run it yourself or ask us to maintain it.
We also provide a post-launch support period for 30 days. If something breaks, we fix it within 4 hours.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated integration tests
- API documentation in Markdown or Swagger
- Sentry error tracking
- Datadog performance monitoring
- Deployment scripts for AWS or GCP
- Post-launch support for 30 days
- Retry logic and error handling
- Rate limit management

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
We hire senior engineers with 8+ years of experience. No junior developers, no offshore teams. Every integration is built by someone who has done it before.
200+ integrations shipped
We have built 200+ integrations across 50+ countries. We have seen every API pattern and error type. You get a solution that works the first time.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance in every integration. Audit logs, encryption, and access controls are standard.
You own the code
Full source code is delivered to your repository. No proprietary frameworks, no lock-in. You can run, modify, or sell the code as you wish.
8-12 week delivery
Most integrations ship in 8-12 weeks. We use agile sprints with 2-week demos. You see progress and can adjust requirements along the way.
